Investment objective & strategy

As of Feb. 27, 2026 · prospectus

Objective. The Fund seeks total return.

Strategy. Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in a portfolio of below investment-grade corporate bonds, commonly referred to as high yield or junk bonds, or unrated securities that Ares Systematic Credit Limited (the Subadvisor) considers to be of an equivalent credit quality, which may be represented by derivative instruments, including futures and swaps. The Subadvisor determines whether a bond is rated below investment grade using a composite rating calculated by assigning a numerical value to those ratings of Moodys, S&P and Fitch which are available for the bond and averaging those amounts to determine the rating. The Fund invests primarily in U.S. dollar denominated securities, including those of … Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in a portfolio of below investment-grade corporate bonds, commonly referred to as high yield or junk bonds, or unrated securities that Ares Systematic Credit Limited (the Subadvisor) considers to be of an equivalent credit quality, which may be represented by derivative instruments, including futures and swaps. The Subadvisor determines whether a bond is rated below investment grade using a composite rating calculated by assigning a numerical value to those ratings of Moodys, S&P and Fitch which are available for the bond and averaging those amounts to determine the rating. The Fund invests primarily in U.S. dollar denominated securities, including those of foreign issuers. Derivative instruments in which the Fund may invest include credit-default swaps and U.S. Treasury futures. The Fund may also invest in exchange-traded funds to manage aggregate portfolio exposures. The Subadvisor follows a systematic investment process based on the testing of investment hypotheses using historical data. The Subadvisors portfolio management team retains discretion with respect to all investment decisions. The Subadvisors investment process utilizes proprietary quantitative models to produce investment recommendations. The Subadvisor generates proprietary insights based on its experience and reasoned intuition to form an investment hypothesis. Using historical market data, the Subadvisor back-tests each investment hypothesis to determine whether actual observations appear consistent with the hypothesis over time. The Subadvisors back-testing process involves the development of research parameters, internal peer review, and consideration of a wide range of analyses. Insights are weighted in the Subadvisors models according to their deemed strength in predicting returns, as determined by the Subadvisor through this testing process. In managing the Fund, the Subadvisor will rely on insights that seek to target idiosyncratic company and security specific risk, which form the basis of security selection decisions and assess metrics such as company strength, company outlook, and credit spreads. In addition, the Fund will rely on the Subadvisors market timing insights which the Subadvisor uses to form a view on the attractiveness of credit and interest rate markets and assess metrics such as market expectations for growth and credit default rates. The Subadvisors models consider data from multiple sources, including issuer-specific and macroeconomic information such as company cash flow, default risk, and earnings expectations. As part of its investment process with respect to each corporate bond portfolio investment, the Subadvisor may consider environmental, social and governance (ESG) factors that it believes may have an impact on an issuer and the value of its securities. The Subadvisor expects that a majority of the Funds total returns in excess of that of the Funds benchmark will be generated from security selection of high yield bonds. Positions are sized based on an optimization which aims to effectively translate the insights gleaned from the Subadvisors proprietary models into portfolio positions. The Subadvisors optimization process seeks to maximize total returns while minimizing expected risk and transaction costs. The Subadvisor conducts performance measurement to seek to validate the accuracy of the investment process with the aim of achieving continuous improvement over time. Duration/Maturity: Duration is one of the characteristics that may be considered in investment process. The Fund does not focus on bonds with any particular duration or maturity and does not seek to maintain the maturity of the Funds portfolio in any particular range. Credit Quality: The Fund invests primarily in below investment-grade debt securities, commonly referred to as high yield or junk bonds, but may invest in other fixed income instruments. As such, the Funds weighted average portfolio quality varies from time to time, depending on the level of assets allocated to such securities. The Subadvisor does not seek to actively invest in defaulted securities.
